Trump: Military 'won't refuse' my orders

Donald Trump says he would have no problem getting the United States military to execute his orders, even ones that might be illegal under international law.

"If I say do it, they're gonna do it," Trump said. "That's what leadership is all about."

Former CIA and NSA Director Michael Hayden said last Friday that if a President Trump were to order the killing of terrorists' families, as he has said he would do, the military would be obliged to disobey.

Asked what he would do if the military disobeyed, Trump seemed to think that would not be an issue.

"They're not gonna refuse me. Believe me," Trump said, remarking that in the Middle East, "they're chopping off the heads of Christians and anybody else that happens to be in the way" and that waterboarding terror suspects would be acceptable. Trump then went on to hit Ted Cruz for vacillating on torture in past debates.

In explaining why killing the families of terrorists would be justified, Trump referred to the families of the 9/11 hijackers. "They knew what was happening. The wife knew exactly what was happening," Trump said.
